How to get the Primary key of annotate Count in django
Hi stackoverflow community, my question is about django annotate. Basically what I am trying to do is to find duplicated value with same values from two different fields in two different tables. This is my models.py class Order(models.Model): id_order = models.AutoField(primary_key=True) class OrderDelivery(models.Model): order = models.ForeignKey(Order, on_delete=models.SET_NULL, null=True, blank=True) delivery_address = models.TextField() class OrderPickup(models.Model): order = models.ForeignKey(Order, on_delete=models.SET_NULL, null=True, blank=True) pickup_date = models.DateField(blank=True, null=True) This is my current code: dup_job = Order.objects.filter( orderpickup__pickup_date__range=(start_date, end_date) ).values( 'orderdelivery__delivery_address', 'orderpickup__pickup_date', ).annotate( duplicated=Count('orderdelivery__delivery_address') ).filter( duplicated__gt=1 ) Based on what I have, I am getting result like this (delivery_address is omitted for privacy purpose): {'orderdelivery__delivery_address': '118A', 'orderpickup__pickup_date': datetime.date(2022, 3, 9), 'duplicated': 2} {'orderdelivery__delivery_address': '11', 'orderpickup__pickup_date': datetime.date(2022, 3, 2), 'duplicated': 6} {'orderdelivery__delivery_address': '11 ', 'orderpickup__pickup_date': datetime.date(2022, 3, 3), 'duplicated': 5} {'orderdelivery__delivery_address': '21', 'orderpickup__pickup_date': datetime.date(2022, 3, 10), 'duplicated': 3} {'orderdelivery__delivery_address': '642', 'orderpickup__pickup_date': datetime.date(2022, 3, 7), 'duplicated': 2} {'orderdelivery__delivery_address': '642', 'orderpickup__pickup_date': datetime.date(2022, 3, 8), 'duplicated': 2} {'orderdelivery__delivery_address': 'N/A,5', 'orderpickup__pickup_date': datetime.date(2022, 3, 8), 'duplicated': 19} Is there a way to get the id_order of those 'duplicated'? I have tried include id_order in .values() but the output will not be accurate as the annotation is grouping by the id_order instead of delivery_address. Thank you in advance -

How do I test a DRF view that updates data on every request?
I'm using Django Rest Framework. I have a model Listing, which has an attribute view_count. Every time data is retrieved from listing_detail_view, view_count is updated using the update method and an F expression. Everything is working as expected, but the test for the view is failing as view_count in the response is always 1 count more. // views.py @api_view(['GET']) def listing_detail_view(request, pk): listing = Listing.objects.filter(pk=pk) serializer = ListingSerializer(listing[0]) listing.update(view_count=F('view_count') + 1) return Response(serializer.data) Note: I'm filtering instead of getting because from my understanding the update method is only available for a QuerySet. // test_views.py def setUp(self): self.listing = Listing.objects.create(id=1) def test_listing_detail_view(self): response = client.get(reverse('listing-detail', kwargs={'pk': self.listing.pk})) listing = Listing.objects.get(pk=self.listing.pk) serializer = ListingSerializer(listing) self.assertEqual(response.data, serializer.data) Here's the AssertionError: {'id': '1', 'view_count': '0'} != {'id': '1', 'view_count': '1'} How do I go about testing this view and its view_count update functionality? -

django form changed_data method: why checked radio button always in changed_data even if not changed?

On my site, a user can shop even if he is not logged in as a guest user. so if a guest user is going to the checkout page he can submit the process and make payment without running into any issues. But when a user is logged in the checkout page returns the error on load! even before writing anything into the form. I am attaching the checkout page code here for you guys to give it a good look.

Django what function is called at the moment the queryset is evaluated?
